YARN-SPECK REMOVER.

Application led November 17 1919.

To all whom t may concern:

Be it known that I, VILLIAM F. MOON, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of lVisconsin, have invented new and useful Improvements in Yarn- Speck Removers, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specication.

The present invention relates to a device for removing lumps of iber or what are commonly termed specks from yarn or thread, previous to its use in a spinning or weaving machine.

One object of this invention is to provide a device of this characterL which will include movable members for crushing or severing the speck from the thread.

Another object of the present invention is to prov-ide a device of this character which will have -movable and yieldable means coperating with a speck positioning member to crush or sever the speck from the thread or yarn.

With the above and other objects in view which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts, substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

In the accompanying drawings I have illustrated two complete examples of the physical embodiment of my invention constructed according to the best modes I have so far devised for the practical application of the principles thereof, and in which:

ing parts broken away and in section to more clearly illustrate the details of construction.

Fig. 6 is a view, part in section and part in elevation, said view being taken on the line 6 6 of Fig. 5.

Fig. 7 is a side view of a still further modified form of my invention, said View having parts broken away and in section, and

Fig. 8 is a view, part in section and part in elevation, said view being taken on the line 8-8 of Fig. 7.

Referring now to the drawings, and more particularly toFigs. 1 to 4L inclusive, the numeral 10 designates generally the frame of the machine which has a plurality of opposed pairs of upwardly extending arms 11 having apertures 1Q in their upper ends, a plurality of opposed pairs of rocking members 13 being medially pivoted to the arms 11 by means of pivots la having their inner ends in threaded engagement with the apertures 12 and their shanks providing supporting journals for the members 13, and means being engaged with the lower ends of the members 13 to rock the same on their pivots 14.

In the drawings, I have illustrated a plurality of speck removing devices, each of which successively acts upon the threads to remove any speck thereon, so that if the first device does not remove the speck it will be removed by another of the devices.

Each of these speck removing devices is mounted on the adjacent arm 11, and consist generally in means for presenting the speck in a position in which it may readily be severed from the thread or yarn by the crushing members hereinafter described.

The means for presenting the speck in position to either side consists of a bed block 15 secured to the frame 10 by means of a fastening member 16 intermediate each opposed pair of arms 11 as best shown in Fig. The bed block 15 is in the form of a stationary member and coacts with the rocking crushing means, to be later described. The yarn or thread 17 is guided through the frame member 10 by means of suitable guiding members 18 and 19, located at each end of the frame, and the thread, in its passage through the frame engages the top of the bed block, and should the speck be on the under side of the yarn, the same will be turned or positioned to the side, there to will be later described.

be severed or crushed from the thread, as As the bed block is insufficient in itself to properly retain the thread upon its top surface in that the thread would possibly become disengaged therefrom, as will be obvious, I so construct by crushing or severing means as to be constantly contacting with the bed block to .provide what may be termed a guide channel for the thread as it passes over each bed block. The cutting or crushing means consists of a pair of movable or rocking knife or crushing members 2O having its severing or crushing edge y'fieldingly held in engagement with the bed block 15, each member being carried by one cf the rocking arms 13. As the operation of each adjacent pair of rocking arms 13 and their crushing members 20 is identical, but one pair` will be described.

The rocking arms 13 disposed on one side of the frame 10 are adapted to be rocked by means of a pitman 21 pivotally secured as at 22 to a connecting rod 23 having pivoted thereto as at 24, the lower` ends of the 'rocking "arms 13 disposed on one sidev of the frame 10 whereby all of the arms 13 on one side of the frame will be rocked in unison. lThe pitman 21 is oscillated by means of an eccentric Vadapted to be carried by a shaft 26 adapted to be VVrotated by a pulley 27 connected wi-th any desired source of power.

As best shown in Fig. 2, the rocking arms 13 disposed on the other side of the frame 10 are also connected in a like manner by means of a connecting rod 23 and a pitman 21. As best shown in Fig. 4, the eccentrics V25 are so positioned on the shaft 26 as to insure the pivotally rocking of the arms 13 of each pair whereby a continuous shearing or crushing movement is effected.

The upper end of each rocking arm 13 is formed with a cylinder or centrally apertured Vcap 28, in which is slidably mounted a hollow sleeve end 29 of a retaining block 30. The retaining block 30 is urged downwardly or outwardly of the cylinder' 28 by means of kan extensile spring 31 disposed in the central bore of the sleeve 29 and having its upper end impinged against a plate 32 engaging the lower end of a tension adjusting screw 33. One of the rocking crushing knife members 20 is secured to the inner face of each retainer 30 by ,means of a screw 34 and has its lower-end yieldingly held in engagement by means of the spring 31 with the adjacent bed block 15.

rIlhe pivot 14 of each arm 13 has itscenter in alinement with the top surface of the adjacent bed block 1-5 to insure the constant engagement of the knife 20 connected therewith with the bed block when the member 13 iis rocked. As before described, the crushing knife members 20 of -each opposed pair of rocking members are oppositely rocked and a continuous cutting action is had. The arm 17 is guided through the frame 10 by the guiding members 18 and 19 and passes between crushing members 20 of each pair, which are spaced apart exactly the thickness of the thread and of the bed block 15, the speck, if on the underside of the thread, will be moved or positioned to one side and there severed or crushed by means of the .members 20 when they are rocked.

Referring now more particularly to Figs. 5 and 6, I employ the same principles as hereinbefore described b v using a vplurality of pairs of opposed stationary arms 35 somewhaty similar in construction 'to the rocking members 13 with the exception that they are rigid with the frame 10 and kin place of the crushing members 20 I employ crushing wheels 36 secured to the .retainers 30 by means of a pivot 37 which permits the 'crushing members 36 to have a free idling movement. In this form of my invention the bed block 15 is in the form of a roll 38 journaled in the frame 10 as at 39 and having a gear 40 mounted on one end thereof which is in mesh with a worm gear 41 fixed to a ,shaft 42, journaled at one side of the frame 10 vand having a gear connection 43 with the shaft 26.

In this form of my invention fthe-bed block rotates and the knife or vcrushing members 36 are lresilie'ntly urged toV engagement therewith ,by means of the springs 31 and the operation thereof is substantially identical with that of the form of my invention hereinbefore described. f n

Referring now more particularly to Figs. 7 and 8 the frame member 10 has a plurality of par-ts of alined shafts 44 having their ends in geared connection with shafts 45 journaled to either side of the frame 10 and in gear connection 43 with the shaft 26.

Each shaft 44 has a crushing wheel or knife member 46 fixed to its inner end and engaging an idling roll or bed block 47 j ournaled in a sliding block or retainer 48 resiliently urged upwardly by means of a spring 49, the spring 49 having a tensioning screw 50 whereby the tensionof the engagement of the bed block 47 with the 'crushing wheels 46 may be regulated. y

The crushing wheels46 of each pair are spaced apart exactly the diameter of the yarn and the operation of this form of myy invention is identical with the vform of my invention hereinbefore described. y

From the foregoing description `taken in connection with the accompanying drawings, it will be at once apparent that I provide means for Ypositively cleaning or removing specks from yarn prior to its use in a spinning or weaving machine.

What I claim for my invention is:

1. A yarn speck remover comprising means for guiding yarn continuously A4in a given direction, and Crushing means operable upon the continuously moving yarn for removing speeks therefrom.

2. In a yarn speck remover, the combina-- tion or" a bed block, means for guiding yarn continuously over the bed block, and a roekable member cooperating with the bed block for removing speeks from the continuously moving yarn.
